Abstract
A washing machine and a method of controlling the washing machine may be provided. The washing machine may include a drum in which laundry are provided and rotated. A laundry amount may be sensed. The drum may operate at a first speed so that a part of the laundry tumbles within the drum and another part of the laundry adheres to the drum or the drum operates at a second speed so that the laundry adheres to the drum according to the sensed laundry amount. Accordingly, at a time of a dehydration cycle, stability of the washing machine and a laundry balancing can be ensured.
Claims (30)
1. A method of controlling a washing machine that includes a drum, the method comprising:
sensing an laundry amount; and when the sensed laundry amount exceeds a first specific value, operating the drum at a first speed so that part of the laundry tumbles within the drum and another part of the laundry adheres to the drum, and, when the sensed laundry amount is less than the first specific value, operating the drum at a second speed so that the laundry adheres to the drum.
sensing an laundry amount; and when the sensed laundry amount exceeds a first specific value, operating the drum at a first speed so that part of the laundry tumbles within the drum and another part of the laundry adheres to the drum, and, when the sensed laundry amount is less than the first specific value, operating the drum at a second speed so that the laundry adheres to the drum.
2. The method of claim 1, further comprising increasing a rotational speed of the drum from the first speed to the second speed when a detected unbalance amount of the drum is a second specific value or less.
3. The method of claim 2, further comprising decelerating rotation of the drum when a detected unbalance amount of the drum is a third specific value or greater.
4. The method of claim 3, further comprising operating the drum in a reverse direction after decelerating the rotation.
5. The method of claim 3, further comprising rotating the drum at the first speed after decelerating the rotation.
6. The method of claim 5, wherein after rotating the drum at the first speed, the method further comprises:
increasing the rotational speed of the drum to the second speed; and operating the drum at the second speed.
increasing the rotational speed of the drum to the second speed; and operating the drum at the second speed.
7. The method of claim 6, further comprising changing a rising slope of speed toward the second speed when increasing the rotational speed of the drum to the second speed.
8. The method of claim 5, further comprising changing a rising slope of speed toward the first speed when the rotational speed of the drum increases to the first speed.
9. The method of claim 1, further comprising decelerating the rotation of the drum when an operation period of the first speed is a specific time or greater.
10. The method of claim 1, further comprising decelerating the rotation of the drum when an unbalance amount of the drum detected while the drum is operating at the first speed is a second specific value or greater.
11. The method of claim 10, further comprising operating the drum in a reverse direction after decelerating the rotation.
12. The method of claim 10, further comprising rotating the drum at the first speed after decelerating the rotation.
13. The method of claim 12, wherein after rotating the drum at the first speed, the method further comprises:
increasing the rotational speed of the drum to the second speed; and operating the drum at the second speed.
increasing the rotational speed of the drum to the second speed; and operating the drum at the second speed.
14. The method of claim 13, further comprising changing a rising slope of speed toward the second speed when increasing the rotational speed of the drum to the second speed.
15. The method of claim 11, further comprising changing a rising slope of speed toward the first speed when the rotational speed of the drum increases to the first speed.
16. A washing machine comprising:
a drum to rotate laundry;
a laundry amount sensor to sense an amount of the laundry within the drum; and a controller to control the drum to operate at a first speed when the sensed laundry amount exceeds a first specific value so that part of the laundry tumbles within the drum and another part of the laundry adheres to the drum, and the controller to control the drum to operate at a second speed when the sensed laundry amount is the first specific value or less so that the laundry adheres to the drum.
a drum to rotate laundry;
a laundry amount sensor to sense an amount of the laundry within the drum; and a controller to control the drum to operate at a first speed when the sensed laundry amount exceeds a first specific value so that part of the laundry tumbles within the drum and another part of the laundry adheres to the drum, and the controller to control the drum to operate at a second speed when the sensed laundry amount is the first specific value or less so that the laundry adheres to the drum.
17. The washing machine of claim 16, further comprising an unbalance amount sensing unit to sense an unbalance amount of the drum, wherein the controller increases a rotational speed of the drum to the second speed when the sensed unbalance amount of the drum, detected when the drum is operated at the first speed, is a second specific value or less.
18. The washing machine of claim 17, wherein the controller decelerates the rotation of the drum when the sensed unbalance amount of the drum, detected when the rotational speed of the drum increases to the second speed, is a third specific value or greater.
19. The washing machine of claim 18, wherein the controller controls the drum to operate in a reverse direction after the drum decelerates rotation.
20. The washing machine of claim 18, wherein the controller controls the drum to rotate at the first speed after the drum decelerates rotation.
21. The washing machine of claim 20, wherein the controller increases the rotational speed of the drum to the second speed and then controls the drum to operate at the second speed after the drum rotates at the first speed.
22. The washing machine of claim 21, wherein when the rotational speed of the drum increases to the second speed, the controller changes a rising slope of speed toward the second speed.
23. The washing machine of claim 20, wherein when the rotational speed of the drum increases to the first speed, the controller changes a rising slope of speed toward the first speed.
24. The washing machine of claim 16, wherein the controller decelerates rotation of the drum when an operation period of the first speed is a specific time or greater.
25. The washing machine of claim 16, further comprising an unbalance amount sensing unit to sense an unbalance amount of the drum, wherein the controller decelerates rotation of the drum when an unbalance amount of the drum, detected when the drum is operated at the first speed, is a second specific value or greater.
26. The washing machine of claim 25, wherein the controller controls the drum to operate in a reverse direction after the rotation of the drum decelerates.
27. The washing machine of claim 25, wherein the controller controls the drum to rotate at the first speed after the rotation of the drum decelerates.
28. The washing machine of claim 27, wherein the controller controls the rotational speed of the drum to increase to the second speed and then controls the drum to operate at the second speed after the drum rotates at the first speed.
29. The washing machine of claim 28, wherein when the rotational speed of the drum increases to the second speed, the controller changes a rising slope of speed toward the second speed.
30. The washing machine of claim 27, wherein when the rotational speed of the drum increases to the first speed, the controller changes a rising slope of speed toward the first speed.
